What percent of the sun is water?
None. The sun is made of pure elements, mostly hydrogen, which fuse together, creating energy in the form of heat and light. When the hydrogen has fused into helium, the helium fuses into the heavier elements. Eventually, a couple billion years in the future, the sun will be made almost entirely of iron, at which point the fusion will cease and the sun will DIE. But you won't be around to see it. At no point does water form without it being immediately consumed and fused into heavier elements.
Here's How:
- Stay out of the sun completely.
- Limit outdoor activities between 10 a.m. and 3 p.m. Play golf, lay in the sun, swim, etc., in the early morning or late afternoon.
- If you must sunbathe get some sun before you visit Hawaii. The Hawaiian sun is very dangerous to pale skin.
- Beware of cloudy days. Clouds and particulate matter in the air scatter sunlight. You can still burn even on a cloudy day.
- Wear a good pair of sun glasses and some kind of protection -- the looser the better -- on your head.
- If you are among those likely to burn, use a sun block with a PF of 15 or greater. An ounce of sun block will effectively cover your entire body.
- Apply sun block at least 15 to 30 minutes before venturing out into the sun and re-apply at least every two hours especially if you have been swimming or perspiring.
- Use sun blocks with higher PFs on areas that need extra protection like the tip of your nose, your ears, the tops of your feet, and your shoulders.
- Do not use sun block on your lips. Instead, use only sun protection products designed specifically for lips.
- Protect your children. Keep them from excessive sun exposure when the sun is strongest and apply sunscreen liberally and frequently to children 6 months of age and older.
- Do not use sunscreen on children under 6 months of age. Parents with children under 6 months of age should severely limit their children's sun exposure.
- Sand and water reflect UV radiation, which means being in the shade under a beach umbrella does not provide complete protection.
- Check with your doctor to make sure that some of the medications you are on do not actually make you more susceptible to sunburn.
Halos are caused by Cirrus Clouds. Thin cirrus clouds plus bright sunlight almost guarantees you seeing something wonderful in the daytime sky.
Cirrus clouds are made of millions of hexagonal ice crystals 3 to 6 miles up in the Troposphere. Each crystal acting as a tiny prism refracting (bending) the sun's light and throwing it elsewhere into the sky.
Because the upper troposphere is almost always below freezing, ice crystals displays can be seen year-round.
But truly good displays in the United States are most common in the fall, winter, and spring when the northern jet stream descends southward, drawing down Arctic air masses whth

What kind of noise does the sun make?
The sun is situated in outer space, which is a vacuum. Sound does not travel through a vacuum, so from where we sit, the sun is silent. It makes no noise.
If you (impossibly) were sitting on the sun, it would be very noisy indeed, with enormous pressures and continual explosions like Hydrogen bombs. Your ears would be destroyed in microseconds by the intensity of the noise.
The sun does make a lot of a different kind of noise. This is electronic noise. The sun makes noise across the whole radio frequency spectrum, which can be picked up on radios.
How much is the weight of the sun?
The sun is about 1.989×1027 tons.
Usually we could count the result by knowing its diameter: 696000 km, and its density:1.409g/cm3
Can you ever be directly under the sun?
No, it is not physically possible to be directly under the sun as the sun is located at the center of our solar system and is extremely far away from Earth. The angle of incidence of sunlight will always vary based on the location on Earth where you are standing.
The amount of energy the Sun pours onto Earth every 10 minutes is roughly equivalent to the world's electricity needs for an entire year.
What was the nearest star to the solar system fifty million years ago and how close was it?
Proxima Centauri, which is currently the closest star to the Sun, was also the nearest star to the solar system 50 million years ago. It was located approximately 4.24 light-years away from the Sun then, just as it is now.
Is the sun drop commical is funny?
The Sun Drop commercial is intended to be humorous with its exaggerated scenarios and quirky characters to make it entertaining and memorable. Its comedic elements are designed to capture viewers' attention and create a playful and light-hearted tone for the advertisement.
Is the sun made out of solid stone?
No, the sun is not made of solid stone. Instead, it is a giant ball of hot gases, primarily consisting of hydrogen and helium. This composition fuels the nuclear fusion reactions that generate the sun's energy and light.
Why are the electrons held in orbit?
Because they are the outer electrons in an atom and they orbit around the nucleus. But you should ask a scientist this question. NOT put it on ask.com.
OR look it up on google.com. it is very likely that you will find something there.
Yes, the sun does not move around itself; instead, it is the center of our solar system around which all the planets, including Earth, revolve in elliptical orbits. Additionally, the sun itself is in motion within the Milky Way galaxy, orbiting the galactic center.
How long does it take a sunspot to disappear on the sun?
Sunspots can last for days to weeks, with an average lifetime of about two weeks. As the sunspot fades, its magnetic field weakens and it eventually becomes indistinguishable from the surrounding surface of the Sun.
Physical properties of the sun?
The Sun is a hot, luminous sphere composed mainly of hydrogen and helium. It has a diameter of about 1.4 million kilometers and a mass about 330,000 times that of Earth. The Sun's surface temperature is approximately 5,500 degrees Celsius, while its core can reach temperatures of around 15 million degrees Celsius.
Was there ever been a solar flare?
Yes, solar flares occur periodically on the Sun. They are sudden, intense releases of energy that can cause disruptions to satellites, radio communications, and electrical grids on Earth. Scientists monitor these events to better understand and predict their impact.
No, the sun is not an autotroph. Autotrophs are organisms that can produce their own food through photosynthesis or chemosynthesis, while the sun is a star that provides energy to support life on Earth.
Where does the sun fall in color classification?
The color of the sun is classified as yellow-white, but it can appear differently depending on factors like time of day, atmosphere, and weather conditions. It may appear more orange or red during sunset and sunrise due to the Earth's atmosphere scattering shorter wavelengths.
Does your sun give light to all the planets in your solar system?
No. Pluto (when it was a planet) was frozen. Neptune is also very cold. Result of no light/warmth.
What are the words start with solar?
Some examples of words that start with "solar" are solarium, solar panel, solar system, and solar energy.
The Sun's core is mostly spherical in shape. It is where nuclear fusion occurs, producing energy in the form of light and heat.
Is the sun about 15 million degrees c?
The center of the sun is about 15 million degrees Celsius. The visible surface is about 5,500 degrees Celsius.
The sun shines bright because it undergoes nuclear fusion in its core, converting hydrogen into helium and releasing energy in the form of light and heat. This process is what provides the sun with its brightness and sustains life on Earth.
